My Hotmail account has been blocked by Microsoft due to “unusual activity,” and I urgently need help. I’ve attempted recovery multiple times, but the phone verification system is not working and all my requests keep getting rejected with the reason "that information I provided was not sufficient enough". I also have an active Microsoft 365 subscription tied to this email, and I can no longer access any of my Office 365 services. This issue needs immediate resolution.51Views0likes1CommentWindows Hello for Business 0x80090010 NTE_PERM
Hi all, I'm encountering an issue with Windows Hello for Business on the latest version of Windows (July 2025 update). The setup process fails during initialisation, and no biometric or PIN options are being provisioned for the user. Environment: Windows version: 11 24H2 Enterprise (latest update) Deployment mode: Hybrid Cloud Trust Hybrid joined devices Symptoms: Users are prompted to set up WHfB but the process fails at the last step with error 0x80090010 Users who already have WHfB authentication methods created can successfully login Event ID 311 & 303 in the User Device Registration logs Screenshots: Troubleshooting so far: Unjoined and rejoined to Entra ID Granted modify permissions on folder in which NGC container would be created Rolled back to June 2025 update (this worked) So it seems like this is caused or related to the latest Windows Update, which is rather unfortunate for us as we are just beginning to rollout WHfB for our organisation. I'm posting here to raise awareness of the issue, if there is a more appropriate place to post then please suggest.15KViews6likes18CommentsLocked out from O365 admin account
Hi! I am locked out from my non-protif organizations O365 admin-account. When trying to login, it ask for the authenticator code, but my authenticator app tells me to login and to login it needs an authenticator code..... I cant contact the O365 support since I cannot login. I found a phone number and talked to some AI bot, but it could not understand when I said the domain name of our organization and shut me down after 3 attempts. So - I have no way to login and handle my organizations account. Can someone please advice how to solve this, or how to get in touch with an actual human being in O365 support???82Views0likes2CommentsNested App Authentication (NAA) token to protect middle-tier server
I'm working on an outlook addin and want to use the NAA accesstoken to validate the user on an api running on a php webserver. The addin runs as a taskepane (created with yo office) with the app only manifest. I have setup NAA to do Microsoft graph calls on behalf of the user. I have used this guid to setup NAA (copy/past) https://learn.microsoft.com/en-us/office/dev/add-ins/develop/enable-nested-app-authentication-in-your-add-in I have setup a php server (not in Microsoft infrastruktur) for a simple API, that handlers MySQL calls and app only calls to Microsoft graph. The php api authenticate itself with a client secret from the Azure app registration. Both are working as expected. Can i use the accesstoken from the NAA, to authenticate the user on the php server? If it can be done how do I validate the token?53Views0likes1CommentMulti-Factor Authentication for people without a Smart Phone?
Howdy, We have a couple people who don't have Smart Phones and need to use MFA. We don't want to use a simple Text Message if we can and prefer to use something a bit more secure. I found there is an Authenticator App for Windows 10 but it doesn't seem to work with O365 accounts. Are there any sort of keyfob dongle or USB dongle thing that work with Office 365 that we can get for people who don't have smartphones? I've used the kind where the number on the fob changes every minute just like an authenticator app would but that was many years ago. If anyone knows something we can use to make this work, let me know. Thanks!94KViews0likes11CommentsExternal people can't open files with Sensitivity Label encryption.
Question: What are the best practices for ensuring external users can open files encrypted with Sensitivity Labels? Hi all. I've been investigating proper setup of sensitivity labels in Purview, and the impact on user experience. The prerequisites are simple enough, creating and configuring the labels reasonably straightforward, and publishing them is a breeze. But using them appears to be a different matter! Everything is fine for labels that don't apply encryption (control access) or when used internally. However, the problems come when labels do apply encryption and information is sent externally. The result is that we apply a label to a document, attach that document to an email, and send it externally - and the recipient says they can't open it and they get an error that their email address is not in our directory. This is because due to the encryption, the external user needs to authenticate back to our tenant, and if they're not in our tenant they obviously can't do this so the files won't open. So, back to the question above. What's the easiest / most secure / best way to add any user we might share encrypted content with to our tenant. As I see it we have the following options: Users have to request Admins add the user as a Guest in our tenant before they send the content. Let's face it, they'll not do this and/or get frustrated. Users share encrypted content directly from SharePoint / OneDrive, rather than attaching it to emails (as that would automatically add the external person as a Guest in the tenant). This will be fine in some circumstances, but won't always be appropriate (when you want to send them a point-in-time version of a doc). With good SharePoint setup, site Owners would also have to approve the share before it gets sent which could delay things. Admins add all possible domains that encrypted content might be shared with to Entra B2B Direct Connect (so the external recipient doesn't have to be our tenant). This may not be practical as you often don't know who you'll need to share with and we work with hundreds of organisations. The bigger gotcha is that the external organisation would also have to configure Entra B2B Direct Connect. Admins default Entra B2B Direct Connect to 'Allow All'. This opens up a significant attack surface and also still requires any external organisation to configure Entra B2B Direct Connect as well. I really want to make this work, but it need to be as simple as possible for the end users sharing sensitive or confidential content. And all of the above options seem to have significant down-sides. I'm really hoping someone who uses Sensitivity Labels on a day-to-day basis can provide some help or advice to share their experiences. Thanks, Oz.286Views0likes20CommentsEscalation Inquiry: IP Logs Request for MS Account
Hello, I am seeking advice regarding a security issue with my Microsoft account. There were unauthorized login attempts on my account between May 23 and May 25, 2025. I submitted a ticket to Microsoft Privacy / Security Incident Response (SIR) regarding IP activity logs. My ticket was created on August 7, 2025 and escalated to the IP/SIR team on August 11, 2025. Since then, I have sent multiple follow-ups, but no response has been received. I also created a new ticket on September 17, 2025, but only received the automatic acknowledgment; no agent has contacted me. I am concerned because the logs are important for verifying my account security and ensuring no unauthorized access occurred. Could anyone advise typical processing times for IP activity requests or suggest ways to escalate this issue effectively? Thank you in advance for any guidance.73Views0likes1CommentAzure AD Health Failing
I am on the latest version of Azure AD Connect (2.5.79.0)... There are no network/DNS/connectivity issues at our site, it seems to me that Azure AD Health Service is having trouble because the endpoint is experiencing a service issue.. Is anyone else having the same problem with failure alerts/etc? I checked by running "Test-MicrosoftEntraConnectHealthConnectivity -Role SYNC" command, the stack trace throws an undocumented error number and complains of rate limiting issues... smells like the server is being overwhelmed or there are other issues slowing down the endpoint/service with the consequence that connections are piling up causing this error: Connectivity Test Step 1 of 2: Testing dependent service endpoints begins ...
